The world's climate goes down the drain and nobody is doing anything against it?

Well... not quite. There is more to be done, that's for sure, every °C counts. But there has been quite some progress in the last years, and Simon Clark was so nice to make a video about it.

A new coating that cools solar panels by absorbing moisture during the night and releasing it during the day results in greater power output and lifespan.

"- It took from the invention of the photovoltaic solar cell, in 1954, until 2022 for the world to install a terawatt of solar power; the second terawatt came just two years later, and the third will arrive either later this year or early next.

- That’s because people are now putting up a gigawatt’s worth of solar panels, the rough equivalent of the power generated by one coal-fired plant, every fifteen hours. Solar power is now growing faster than any power source in history, and it is closely followed by wind power—which is really another form of energy from the sun, since it is differential heating of the earth that produces the wind that turns the turbines.

- Last year, ninety-six per cent of the global demand for new electricity was met by renewables, and in the United States ninety-three per cent of new generating capacity came from solar, wind, and an ever-increasing variety of batteries to store that power.

- In March, for the first time, fossil fuels generated less than half the electricity in the U.S. In California, at one point on May 25th, renewables were producing a record hundred and fifty-eight per cent of the state’s power demand. Over the course of the entire day, they produced eighty-two per cent of the power in California, which, this spring, surpassed Japan to become the world’s fourth-largest economy.

- Meanwhile, battery-storage capability has increased seventy-six per cent, based on this year’s projected estimates; at night, those batteries are often the main supplier of California’s electricity. As the director of reliability analysis at the North American Electric Reliability Corporation put it (...), “batteries can smooth out some of that variability from those times when the wind isn’t blowing or the sun isn’t shining.” As a result, California is so far using forty per cent less natural gas to generate electricity than it did in 2023..."

Solarpower has won, not because it is alternative or woke, but because of economy. And it will keep winning with still improving panels, becoming thinner and easy to use everywhere, battery technology is also still improving.

ENG: scroll down to The New Yorker article on renewable energies reshaping the world, whether autocrats like it or not.

ESP: "El año pasado, el noventa y seis por ciento de la demanda mundial de nueva electricidad se cubrió con energías renovables, y en Estados Unidos el noventa y tres por ciento de la nueva capacidad de generación procedió de la energía solar, eólica y de una variedad cada vez mayor de baterías para almacenar esa energía.

En marzo, por primera vez, los combustibles fósiles generaron menos de la mitad de la electricidad en Estados Unidos. En California, en un momento dado, el 25 de mayo, las energías renovables produjeron la cifra récord del ciento cincuenta y ocho por ciento de la demanda eléctrica del estado. A lo largo de todo el día, produjeron el ochenta y dos por ciento de la electricidad de California, que esta primavera superó a Japón y se convirtió en la cuarta economía del mundo. (... muchos más ejemplos en el artículo )

Esto sugiere que existe la posibilidad de una profunda reordenación de los sistemas de poder de la tierra, en todos los sentidos de la palabra "poder", ofreciendo un freno plausible no sólo a la crisis climática sino también a la autocracia. En lugar de depender de depósitos dispersos de combustibles fósiles -cuyo control ha definido en gran medida la geopolítica durante más de un siglo-, estamos avanzando rápidamente hacia una dependencia de fuentes de suministro difusas pero ubicuas."

Interesante, no solo lo dicho, sino que sea El New Yorker quien lo diga...

"Using some mapping we found that the rooftops of 14 of Auckland's largest buildings would have the same land area as the largest solar farm under construction [in Aotearoa]. So we could potentially be distributing those solar panels in our city ..."

"Scientists have used solar power to heat an object to 1,800 degrees Fahrenheit (1,000 degrees Celsius) — hot enough to power a steel furnace. The proof-of-concept study, published May 15 in the journal Device, demonstrates how solar energy could replace fossil fuels in high-temperature manufacturing processes, such as smelting steel."
